1.1 What is the IZAR CENTER?

The IZAR CENTER is an M-Bus level converter / repeater, which as “memory” variant can also be used as M-Bus master. In addition to reading M-Bus devices automatically and independently, the memory variant can also monitor the data read out and react to alarm conditions. The meter data stored in the IZAR CENTER can also be cyclically uploaded to an FTP server.

1.2 What is the M-Bus?

The M-Bus (Meter Bus) is an inexpensive bus system used for reading resource meters, such as water meters, heat meters and electricity meters. The M-Bus was developed by Prof. Ziegler at Paderborn University in cooperation with the companies Texas Instruments and Techem. It has been adopted as the European standard for all meters except electricity meters.

The variants without memory can be used for the following purposes:

• Direct reading of M-Bus devices via a PC/laptop

• As repeater for connecting more than 250 M-Bus devices to an M-Bus network or if the M-Bus lines are to bridge large distances (several kilometers)

The variants with memory offer the option of reading M-Bus devices automatically at adjustable intervals, storing the data and sending this data over the interfaces on request. The collected data can also be automatically uploaded to an FTP server. The IZAR CENTER must be connected via the LAN interface or a special GPRS modem for this purpose.

An IZAR CENTER with memory can also monitor the M-Bus devices during automatic reading and send an alarm report and/or alarm action in the event of an error.

2 Installation

2.1 Power supply

The IZAR CENTER is equipped with a universal power supply and can be operated with mains voltages of 110 – 230 V AC (50..60 Hz).

2.2 M-Bus

2.2.1 M-Bus output These terminals can be used to connect one or more pairs of wires to M-Bus devices. A standard telecommunications cable can be used as M-Bus cable. The connection is not polarity conscious. The maximum number of M-Bus devices that can be connected to an IZAR CENTER depends on the type of IZAR CENTER used. See Table 1-1

The following types of connection are permitted:

• Star topology

• Bus topology

• Combination of bus and star topology

2.2.2 M-Bus input (Slave-In)

The M-Bus input is only intended for an IZAR CENTER without memory. An M-Bus signal source (e.g. another IZAR CENTER or IZAR CENTER Memory) can be connected to this input. All signals at this input to the IZAR CENTER are passed direct to the M-Bus output at the same speed.

This makes it possible to connect several IZAR CENTERs in succession for reading more than 250 M-Bus devices or if the M-Bus cable network contains excessively long lines. Connecting several IZAR CENTERs in succession is called a cascade connection. A cascade connection enables an M-Bus network to be expanded to any desired size.

Fig. 2-1 M-Bus cascade connection

Please note: Only one IZAR CENTER Memory can be used in a cascade connection. This must then be placed at the start of the signal chain (see Fig. 2-1 M-Bus cascade connection

2.3 USB

The IZAR CENTER has a USB interface (USB B-socket) on the bottom side of the device for direct connection to a PC/laptop. It is not necessary to install a special driver before connecting.

Please note:

If you use Windows XP, you must remove the USB connector after the PC has recognized the device and then reinsert the connector (this is only necessary once).

2.4 LAN

The LAN connection (RJ-45 socket) is located on the top side of the IZAR CENTER.

Use this connection if you want to read out the IZAR CENTER via TCP/IP. In addition to direct reading/ configuration of the IZAR CENTER and the M-Bus devices, the IZAR CENTER can automatically export data to an FTP server and send e-mails as alarm messages.

The LAN connection supports dynamic IP address allocation (DHCP) and can also be configured with a static IP address. Use the IZAR CENTER software for configuration of these settings.

DHCP is activated by default. This means that the IZAR CENTER automatically attempts to get an IP address. In this case, it is not clear which IP address the IZAR CENTER has been assigned by the IT system. If you wish to find your device in the PC network, you can use the TCP/IP search in the IZAR@CENTER software.

It is naturally also possible to connect the IZAR CENTER direct to the PC via a LAN cable, but suitable static IP addresses must be assigned to the PC and the IZAR CENTER for this purpose.

Please note: Connect the LAN connection of the IZAR CENTER before inserting the mains plug.

2.5 Serial

The serial (RS232) interface can be used either for the direct connection of a PC or for connecting a modem. The two functions cannot be used at the same time. Use the IZAR CENTER software for setting the use of the serial interface.

2.5.1 RS232 – PC

If the serial interface is set to “PC” mode, you can connect the IZAR CENTER direct to a PC. You do not need to install a driver on the PC.

Interface speeds (baud rates) of 300…57600 bauds can be used for communication with the IZAR CENTER.

Baud rates of 300…9600 bauds can be used for communication with M-Bus devices.

Please note: At baud rates > 9600 bauds, communication signals are not passed through to the M-Bus outputs (no communication with M-Bus devices).

The IZAR CENTER automatically detects the baud rate used (setting is not necessary).

2.5.2 RS232 – modem

If the serial interface is set to “Modem” mode, you can connect a modem to the IZAR CENTER.

You can use the following types of modem:

• Analogue modem

• GSM modem

• GPRS modem

Attention: To ensure full and reliable operation, please use only modems specified by HYDROMETER (see Suitable types of modem). No support is available for other types/models of modem.

3 Configuration

3.1 Principles

3.1.1 Basic operation/architecture

As already mentioned above, an IZAR CENTER without memory serves only as a level converter /repeater. The operation of this type is therefore relatively simple compared with the IZAR CENTER Memory. As an IZAR CENTER Memory is equipped with functions like automatic reading of M-Bus devices and parameter monitoring/alarm handling, it works with internal lists. The following figure shows the architecture:

Automatic M-Bus device reading

Alarm functions

Device list/ limits

(max. 1000 devices)

Data memory

Auto device reading

Send SMS Send e-mail

Execute M-Bus alarm action

Address list (Alarm addressees)

Text list (Alarm texts)

Action list (M-Bus commands)

Alarm value monitoring

Fig. 3-1 Function model of IZAR CENTER Memory


11

The IZAR CENTER requires 4 internal lists:

• Device List: Contains the information indicating which M-Bus devices are to be read and how often, and optional alarm limit values.

• Address List: This list is comparable with an address book and contains the name, e-mail addresses and telephone numbers of persons to be notified in the event of an alarm.

• Text List: Freely definable texts that are to be sent in addition to the measurement data in an e-mail or SMS in the event of an alarm.

• Action List: The IZAR CENTER can send a command to an M-Bus device in the event of an alarm. This list defines which device is to be addressed if an alarm occurs and which command is to be sent to the device.

Only the Device List is required for recording readings. All four lists are required if you wish to use all the alarm monitoring functions of the IZAR CENTER. If you only want to send an SMS or e-mail as alarm notification, the Action List is not necessary.

How to create and manage the respective lists is described in Chapter 3.3.1.

3.1.2 Installing the IZAR@CENTER software

Install the IZAR@CENTER software. This software can be found on the enclosed HYDROMETER system software CD and on the HYDROMETER website: http://www.hydrometer.com/systems/download.html The website contains the latest version of each software. The PC must fulfil the following system requirements:

• Pentium PC, 500 MHz or higher

• At least 256 MB RAM

• Approx. 50 MB of free hard disk space

• Operating system: Windows XP/Vista

• Free RS232 interface (if IZAR CENTER is to be connected direct to PC or read via modem)

• Free USB interface (if IZAR CENTER is to be connected direct to PC )

• LAN interface (if IZAR CENTER is accessible via LAN)

You need local administrator rights on the PC during the installation. After the installation, you will see a new program link with the icon on your desktop and in the Windows Start menu.

3.1.3 Starting the IZAR@CENTER software

If you have installed and connected the IZAR CENTER as described above, you can now start the configuration of your system. For the initial installation, we recommend using the USB connection for configuring the system.

Proceed as follows to set up a new dial-in modem connection:

• Select Modem option.



14

• Select the serial COM port to which the device is connected under Port.

• Set the Speed to the desired baud rate to be used by your PC to the modem connected (this is not the transmission speed of the switched connection). The default setting is 19200 bauds.

• Enter the telephone number for reaching your IZAR CENTER in the Telephone Number field.


Please note: If your PC is connected to a telephone system, please insert the digit for obtaining exchange line access as the first digit in the Telephone Number field. Some telephone systems also need a dial pause before dialling the actual telephone number. To create a dial pause, simply insert a comma between the exchange line access digit and the actual telephone number. Here is an example:

Telephone no: 0, 08101 654321 actual number dial pause (1 comma = 1 second)

exchange line access digit

3.1.4.4 TCP/IP (LAN)

Proceed as follows to set up a new LAN connection:

• Make sure your PC is in the same network (same subnet) as the IZAR CENTER.

• Select the TCP/IP option.


• Press the Search button and wait until the IZAR CENTER software has completed the automatic network device search (approx. 5 seconds).

• Click the Address field and select your IZAR CENTER in this field. Here is an example:

Compare the MAC address in the right half of the search results with the address printed on the device and select the corresponding entry here in the list. Alternatively, you can enter the IP address of your IZAR CENTER direct if known, instead of the automatic search.

• “FTP”: An FTP Upload is in progress

• “E-Mail ALARM”: Sending an alarm e-mail is in progress

• “SMS ALARM”: Sending an alarm SMS is in progress

• “MBus ALARM”: An M-Bus alarm action (M-Bus command) is executed


17

Location Address may be used as system or plant identifier. The usage of the location address is optional and serves merely for better identification of the system (if device is connected via USB location address will be displayed as trailing addition to the USB identifier in the connection setting field of IZAR@CENTER software)

The Period to read is part of settings fort he memory readout and is described in 3.4.1

3.1.5 Reading device list

This operation is optional and only makes sense if you have already written a device list into the IZAR CENTER.

• Press the button (Read internal status values and device list).

• The existing device list is shown in the program.

3.2 Reading devices direct

3.2.1 Standard M-Bus devices

There are two ways of reading the devices connected to the M-Bus output direct and immediately. Entering the M-Bus address direct or reading with the aid of a device list. Direct entry is faster. If several different devices are to be read, using a device list is the better alternative, but a device list must be created first (see 3.3.1). The first way is briefly described below.

• First select the “General: Read device” program view by pressing the button.

• Select the M-Bus baud rate to be used (see figure). This baud rate is usually either 300 bauds or 2400 bauds

• Now enter the M-Bus secondary address of the device to be read in the “Secondary address” field. The secondary address is an 8-digit number and is shown on the housing of most M-Bus devices. Press the button (General: Read with secondary address). Alternatively, you can enter the primary address of the M-Bus device in the “Primary address” field, if known. If only one M-Bus device is connected, you can also use the M-Bus broadcast address (“254”) here. In this case, press the button (General: Reading using primary address) after entering the address.

• Wait until the M-Bus device has been read. If the reading process was successful, the device data are shown in the data read field in the bottom right corner of the window:


18

If the device was not read successfully, this can have several causes. Possible causes of failure and their clearance are shown at 5.1 (M-Bus devices

• ).

• If desired, you can add the device found to the device list if the reading process was successful. This is done by pressing the button (General: Add found devices to device list).

3.2.2 HYDROMETER M-Bus radio receiver

If you use HYDROMETER M-Bus receivers in your system, you can also configure and read these devices with the IZAR@CENTER software. For this purpose, you must first select the M-Bus receiver key in the program settings. Proceed as follows:

• Click the button (Settings). The IZAR CENTER Settings window appears.

• Select the “Default 868 MHz Receiver Key” option at the bottom right if you use the standard radio key in your radio network. If you use another radio key, select the “868 MHz key” option and enter the radio key you use to operate your HYDROMETER radio system in the input field on the right of the option.

• Close the window by pressing OK.

• A new view icon is now shown in the main window.

Proceed as follows to read or configure a connected M-Bus receiver:

• Change to the M-Bus 868 MHz radio receiver view. This is done by pressing the button or ALT+5 keys.

• If several receivers are connected to this M-Bus network, enter the 8-digit M-Bus address of the receiver you would like to connect to in the radio receiver address field. The address is printed on the receiver. If only one radio receiver is connected, it is not necessary to enter an address.

• Press the button (Read internal state values) to connect the M-Bus receiver. Alternatively, you can use the button (Read internal status values and device list). The receiver’s list of received devices is then read in addition to the status values of the receiver.


19

• If you would like to transfer devices from this list to your device list, click (Add found devices to device list). A new dialogue box appears:

Select either “All devices found” or “Only selected devices” to transfer the devices to the IZAR CENTER device list. If you wish to add several or only certain devices, you can also select the devices beforehand in the M-Bus receiver device list. As familiar from other applications, use the or Ctrl key if you wish to select several devices from the list.

• Press the OK button to transfer the devices to the IZAR CENTER device list.

• The IZAR CENTER device list now contains the newly added devices.

3.3 Reading devices automatically

As described above, your IZAR CENTER Memory needs a device list to be able to read M-Bus devices automatically and record and monitor their data. This list contains several items of information:


20

• Which devices are to be read (e.g. device type)?

• How often is the device to be read (reading interval)?

• Name of device in plain text, for easier identifying of this device.

• Which M-Bus baud rate is to be used to address the device?

• How often is a reading process to be repeated in the event of an error?

• Which values of each device are to be monitored and what action is to be taken in the event of an alarm?

The first step is to create a device list. There are several possibilities for this:

• Automatic M-Bus device search (recommended, see 3.3.1.1)

• Manually searching, finding and adding of M-Bus devices (see 3.3.1.2 Manual device search)

• Manual adding of devices to the device list (see 3.3.1.3 Manually adding a device

• )

• Loading an existing device list from a file (see 3.3.1.4 Importing device list from a file)

3.3.1 Creating a device list

3.3.1.1 Automatic device search If you have never created a device list before or if you are taking a new system into operation, the automatic device search is recommended. Here the PC software searches for all possible M-Bus addresses and shows the M-Bus devices found on completion of the search. Note that a few M-Bus devices do not support a device search.

The duration of an automatic device search mainly depends on the number of devices connected, the M-Bus baud rate and the type of connection to the PC. A device search over a modem connection can take a very long time and is therefore not recommended for large systems.

The following steps are necessary to create a device list using a device search:

1. Set up a connection to your IZAR CENTER (see 3.1.4 Connecting to the IZAR CENTER

2. Change to the view (Read device).

3. Click the button (M-Bus device search). The M-Bus device search dialogue box appears:


21

You can accept the suggested settings or set your own search criteria. Press the OK button to start the search. The status display shows the address range currently being searched:

The devices found are shown in the list at the bottom right on completion of the search:


22

4. Select the devices you wish to add from the list of search results or transfer all devices found to the IZAR CENTER device list.

5. Click the button (Transfer devices found to device list). The “Transfer devices found” dialogue box appears:

6. Click the OK button to transfer all devices found to the IZAR CENTER device list. If you have not changed any filter settings in this dialogue box, no duplicates are created. This means that devices already contained in the list are not created as duplicates.

7. Repeat steps 1 to 6 if necessary, e.g. to also find 300-baud devices. This is mostly necessary if some of the M-Bus devices connected are set to another baud rate and not equipped with automatic baud rate detection.

8. Once you have added all the devices to your IZAR CENTER device list, you must write this list into the IZAR CENTER. See 3.3.1.5 Writing device list.

3.3.1.2 Manual device search If a device list is already created in the IZAR CENTER and, for example, only a new device is to be added, you can also search manually for an M-Bus device instead of the time-consuming automatic device search. For this purpose you only need the M-Bus secondary address or the primary address of the M-Bus device. The M-Bus secondary address is an 8-digit number usually printed on the M-Bus device. To add the device to an existing device list, connect to the IZAR CENTER and load the existing device list into the software. See 3.1.4 Connecting to the IZAR CENTER

You can then search for a device manually and add it to the device list as described in 3.2 Reading devices direct

3.3.1.3 Manually adding a device

You should only use this option if you know exactly which M-Bus device type is installed in your system and the settings for addressing it. This procedure is therefore only recommended for experts.

• Connect to the IZAR CENTER as described in 3.1.4 (Connecting to the IZAR CENTER

• .

• Change to the Device list program view by pressing the button (ALT+2).


23

• Read any existing device list from the IZAR CENTER using the button (Read device list).

• Press the button (Add new device to list) to add a new entry to the device list.

• First select the right address in the input mask (usually “secondary”).

• Enter the address of your M-Bus device in the …address field. The following example shows the entry of a secondary address.

• Now select the relevant M-Bus device in the field with the entry <unknown meter type>. If the relevant entry is not available, first check that the latest version of the IZAR@CENTER software is installed. After you have selected the device from the list, the 3 fields below the device selected and the Baud rate and Selection telegram fields are automatically filled with the right data:

• Enter a suitable plain text description of the device under Description. This description helps you to identify the device more easily. It is also used when sending an alarm report.

• In the Read interval field define how often the device is to be read automatically by the IZAR CENTER. See also 3.3.1.5 (Writing device list)

• The Read out retries field is for defining how often the IZAR CENTER is to repeat the reading of a device in the event of a reading error.

• Press the button (Transfer new device to device list). The new entry now appears in the IZAR CENTER device list.

3.3.1.4 Importing device list from a file

If you have already generated a device list and saved it as a file, you can also reload this list from the file, modify it as necessary and write it into the IZAR CENTER. It is also possible to load a HYDRO CENTER device list file and import this into the IZAR CENTER. This is unfortunately not possible in the other direction. To load a device list from a file, click (Load device list from a file).

You can now modify the loaded device list (delete or add entries, change description…) and write the device list into the IZAR CENTER.


24

3.3.1.5 Writing device list

If you have created a device list as in the options described above, you now define the following information for the devices to be read:

• Unique name (Description) of the M-Bus device.

• How often is the device to be read (Read interval)?

• How often is the IZAR CENTER to repeat the reading process in the event of an error (Read repeats)?

Proceed as follows:

• Change to the Device list program view by pressing the button (ALT+2).

• Select a device in the IZAR CENTER device list.

• Enter a unique name for your device in the Description field. This name is used for finding the device more quickly in the list, which is especially useful in large systems with many M-Bus devices.

• In the Read interval field define how often the M-Bus device is to be read automatically by the IZAR CENTER. The following table shows the possible read intervals:

Read interval Meaning (read M-Bus device)

-------- Deactivated (no reading)

1 m Every minute

5 m Every 5 minutes

15 m Every 15 minutes

1 h Every hour

3 h Every 3 hours

6 h Every 6 hours

12 h Every 12 hours

1 d Every day

1.x. + 15.x. Every 1st and 15th day of the month (at 00:00 each time)

You can also give several or all devices in the list the same read interval without having to select every device individually. First switch to the list view of the device list by clicking the icon (Show devices in tabular form). As familiar from other applications, you can then select several devices in the list using the (Shift) or Ctrl key. Now click the button (Use reading interval to all selected devices).


25

• The Read out retries field is for defining how often the IZAR CENTER is to repeat the reading of a device in the event of a reading error. You can also give several or all devices in the list the same number of Read out retries without having to select every device individually by clicking the icon (Show devices in tabular form). As familiar from other applications, you can then select several devices in the list using the (Shift) or Ctrl key. Now click the button Use read out retries for all selected devices).

You have now compiled all the required information and the device list is complete. Finally, you must press the button (Write device list) so that the IZAR CENTER can use this list. This list is now written into the IZAR CENTER over the selected interface connection.

You can now make a backup file of this list if required. This is done by pressing the button (Save device list to a file), defining a file name and pressing the Save button. This file can then be used to create the list again at a later date.

3.3.1.6 Changing a device list

If your IZAR CENTER is already operating successfully and, for example, a new M-Bus device is to be connected or an old device replaced with a new device, proceed as follows:

• Add a new device Connect to the IZAR CENTER and first load the existing device list in order to modify this list. This is done by pressing either (Read internal status values and device list) or (Read device list) Use one of the ways described above to find your M-Bus device in the M-Bus network (see 3.3.1.1, 3.3.1.2, 3.3.1.3). Add the new device to the list.

• Delete a device from the list To delete an old M-Bus device from the list (e.g. on replacement of device), load the existing device list, select the device to be deleted in the list and press the button (Delete device). If you wish to delete the whole device list, select the top entry in the device list “Devices (all:)” and press the button (Delete device).

Finally, define the read settings as described in 3.3.1.5 and write the new modified device list into the IZAR CENTER.

3.3.1.7 Service mode

Service mode on: All automatic reading processes and the alarm monitoring are stopped and the M-Bus is activated exclusively for the external interfaces.

Service mode off (normal operation): All automatic reading processes are carried out as usual, the alarm monitoring is activated and the M-Bus can be blocked for the external interfaces when a device is being read.


26

Access to the IZAR CENTER itself is independent of the service mode. This means that you can change the settings on the IZAR CENTER or read data from the memory at any time.

Detailed description: If you have already written a device list into your IZAR CENTER, this is processed cyclically as desired.

If you try to access the M-Bus yourself (e.g. read device or device search) while processing is in progress (M-Bus device is currently being read automatically), this may fail as the automatic processing of the device list has absolute priority on the M-Bus.

To be able to access the M-Bus yourself, you must deactivate the automatic processing (temporarily). The IZAR CENTER is equipped with a Service mode for this purpose.

Pressing the button (Service mode) activates or deactivates the Service mode at the IZAR CENTER.

-> Service mode on = full access to M-Bus (automatic reading deactivated) If you have activated the Service mode, the status display of the IZAR@CENTER software is shown with a red background colour:

-> Service mode off = normal operation (automatic reading activated) If you have deactivated the Service mode, the status display of the IZAR@CENTER software is shown with a yellow background colour:

Important: If you wish to access the M-Bus network direct or change an alarm/device list, the Service mode should be activated first!

3.4 Retrieving data collected

After reading and saving, meter telegrams can be read from the internal memory direct over one of the interfaces (serial, USB, LAN) or transmitted automatically and time-controlled to an FTP server.

The internal data memory of the IZAR CENTER is a “ring memory” and can store approx. 500,000 readings. The data memory cannot overflow and all data are stored permanently. When the memory is full, the IZAR CENTER automatically overwrites the oldest readings in the data memory with the new reading data.

3.4.1 Reading via device interface

You can retrieve the stored data over all interfaces (USB, LAN, modem, RS232) of the IZAR CENTER.


27

Proceed as follows:

• Connect to the IZAR CENTER (as described in one of the options at 3.1.4) and read the status values of the IZAR CENTER.

• Read the device list as described in 3.1.5 if desired.

• Define how much data is to be read. This is done in the “Status” view by entering the number of minutes, hours or days to be read from the present time back into the past. You can enter values from 0 to 65535.

If you select “0” as setting, the complete memory is read. Please note that this process is of limited use and takes a very long time. Write this setting into the IZAR CENTER by pressing the button.

• Change to the “Read device” view by pressing the button.

• Start reading the data by pressing the button (Read data logger memory).

• Now wait until the status display shows “Operation successful” or if desired cancel the reading process by pressing the button.

• If reading data was available in the data memory, this is shown in the right half of the program window: You can select various views with the tabs:

Readings below each other (default) Reading times in columns

M-Bus device addresses + reading times in columns HYDRO-NET import format

• If you only wish to see the data from one or several selected M-Bus devices, you can now select these devices in the device list (left) by clicking the icon (Show devices in a table). As familiar from other applications, you can then select several devices in the list using the (Shift) or Ctrl key. If you wish to see the data for all M-Bus devices again, just select the first entry in the device list again “Devices (all):”.

• You can also filter the times and data by pressing the button (Filter options). The filter does not delete the data in the background and only the filtered data are shown.

• You can now save these data in a file by pressing the button (Export meter readings to a file). This creates an .xls (Excel®) file.


28

• You can copy the currently displayed data to the Windows® clipboard using the button.

• The button (Export meter readings to HYDRO-NET) is for exporting the reading data direct to the HYDROMETER HYDRO-NET® software (HYDRO-NET must be installed on your PC for this purpose).

3.4.2 Automatic uploading using FTP

The IZAR CENTER can also upload its reading data cyclically to an FTP server. An .xml file is created for this purpose, which you can process with the HYDROMETER HYDRO-RADIO© software, for example.

A number of settings must be made for transferring stored telegrams to an FTP server automatically.

• Setting the “upload interface” (LAN or GPRS)

• Configuration of the upload interval

• Setting the FTP server connection data (server URL or IP, login data, directory)

• Checking the correct settings for TCP/IP if LAN is used as upload interface

Proceed as follows:

• Change to the “Status” view and connect to the IZAR CENTER.

• Press the button to proceed to the next settings. The settings are read out of the IZAR CENTER automatically.

• Go to the Main FTP tab and enter your connection data for the server. In the URL field you can enter a URL (e.g. www.myServer.com) or an IP address.

• Enter your server login data in the Username and Password fields.

• An existing valid directory on the FTP server must be entered in the Directory field. If subdirectories are used, insert a / (slash) between the directory names. It is not necessary to enter a slash before or after. Example: Your server is www.myServer.com and you have your own directory “MyFolder”. Here you have created a subfolder called “IZAR_CENTER_Upload” for uploading the IZAR CENTER export data. You would then enter “MyFolder/IZAR_CENTER_Upload” in the Directory field.

• Now press the button (Write parameter)

• Select the desired upload interface in Upload-Interface field. For the FTP upload you can use either the LAN interface (integrated) or a special external GPRS modem (not supplied with equipment).

• Use the Upload interval field to define how often (cyclic) an FTP upload is to be performed (0..65535 days/hours/minutes). The “0” setting deactivates the automatic upload in the same way as setting the days/hours/minutes to deactivated.

• Extended FTP settings gives you the option of defining the maximum permissible number of bytes (data amount) or telegrams (readings) per upload. These settings can be useful for limiting the maximum data transfer volume if GPRS is used as upload interface. Please note that data gaps can occur between the uploaded


29

exports if the setting is wrong.

• Write the upload interval and interface settings into the IZAR CENTER using the button (Write upload cycle).

• You have the option of entering a second FTP server on the Backup FTP tab. If the upload to the Main FTP server fails, the IZAR CENTER tries to upload to the Backup FTP server. It is not possible to upload to both servers. This means, for example, that the same data cannot be uploaded to the Backup FTP server if the upload to the Main FTP server was successful. Set and write the settings for the Backup FTP server in exactly the same way as the settings for the Main FTP server.

• If you have selected the LAN as upload interface, make sure you have adapted the LAN interface settings as described in 4.5.

• If you have selected the GPRS as upload interface, make sure you have adapted the GPRS connection settings as described in 4.2 and the Serial interface settings (see 4.1).

After all the settings have been written into the IZAR CENTER, the automatic upload to the FTP server is initialized.

Operation of automatic upload:

In the first upload attempt the IZAR CENTER transfers all the stored data to the FTP server. Each additional upload only transfers the data to the server that has not yet been stored on the server, i.e. all data from the time of the last upload to the present time.

After writing all the required settings for the FTP upload, you have the possibility of performing a test upload by pressing the button (Test).

The software then immediately reports “Operation successful”. This means that the upload will start in a few seconds. When the upload is completed depends on the amount of data to be uploaded. The upload is completed when the target folder on the FTP server contains the .xml and a .rdy file with the same end number on the FTP server. Both files also have a current time stamp (date of creating the file).

The files created during the upload have the following file name structure:

MAC address of IZAR

CENTER Continious number

(3-digit) File type (ending)

00204AA9BD3E_023.xml


30

Example after a successful upload:

Fig. 3-6 Uploaded data on the FTP server

Note on timing:

The upload interval defines the time intervals at which the uploads are to be carried out after saving the settings. Example: The internal clock of the IZAR CENTER shows the current time as 12:37 and you now save an FTP upload interval of 60 minutes. Subsequent uploads will now be carried out at 13:37, 14:37, etc. If you allow several IZAR CENTERs to upload to an FTP server, this mechanism prevents overloading problems with the FTP server as the uploads are distributed over a period of time and not all IZAR CENTERs upload to the FTP server at once.

3.5 Alarm monitoring

The IZAR CENTER provides monitoring of values for every M-Bus-compatible meter in the device list. Up to two alarms can be assigned to each meter in the device list.

Maximum 20 alarm entries are available for “intelligent consumption recording” (see Intelligent determination of consumption).

The values are checked every time the meter is read automatically. The alarm response time is accordingly dependent on the read interval of the meter. The configured alarm action is executed when the alarm condition occurs.

An alarm action (SMS, e-mail or M-Bus command) is only executed if no alarm was detected at the last reading time, i.e. the alarm condition was not fulfilled last time. An alarm is therefore always generated on the transition from “alarm condition not fulfilled” → “alarm condition fulfilled”.

If more than 20 alarms are detected during processing of the device list/meter reading, the 21st and all subsequent alarms are not processed in this read cycle and do not lead to any alarm action. If the alarm condition is still fulfilled at the next read interval, an alarm is detected again and (provided there are less than 20 alarms currently being handled) the configured alarm mode is executed.

3.5.1 Alarm types

3.5.1.1 Monitoring of status information (mask)

All M-Bus-compatible meters provide response telegrams containing status information that shows meter-dependent states (sensor break, air in measuring path,…). This information is


31

transmitted in a ‘status byte’ in the response telegram and can be used for monitoring purposes. The function of the individual bits or a status byte value is only partly standardized and thus dependent on the meter used.

3.5.1.2 Monitoring instantaneous values

The most frequent monitoring application is the configuration of instantaneous value monitoring. Up to two values of a meter telegram can be monitored for falling below or exceeding a specified limit. The following are examples of typical instantaneous values of a meter:

• Flow rate (m³/h)

• Volume

• Temperature

• Energy

• …

Consumption monitoring can usually be implemented with the instantaneous consumption values provided by many meters. Resorting to intelligent determination of consumption is therefore only necessary in special cases (see below).

3.5.1.3 Intelligent determination of consumption values

In rare cases a meter does not provide the desired consumption value as an instantaneous value (e.g. flow rate), but only as a meter count. In such cases it is possible to determine consumption from two consecutive meter counts, which is then used as a limit for an alarm.

The basis for determining consumption is the read interval. The values of two consecutive readings are used to calculate a consumption figure for the read interval and compared with a configured limit. The comparison initiates an alarm depending on the configuration (below or above the limit).

3.5.2 Alarm modes

Up to 3 alarm modes can be configured for an alarm.

• Alarm SMS: An SMS is sent to one of 10 telephone numbers in the event of an alarm. To be able to send an SMS, it is necessary to operate a suitable GSM modem at the serial port and configure the serial interface for modem operation.

• Alarm e-mail: An e-mail is sent to one of 10 e-mail addressees if an alarm occurs. To be able to send an e-mail, it is necessary to set the upload interface to LAN. E-mails are not sent over GPRS.

• M-Bus action: An alarm causes an M-Bus command to be sent to an M-Bus device. A condition for this alarm mode is that the device addressed can be reached over the M-Bus master output of the IZAR CENTER.

3.5.3 Alarm lists

The configuration of alarms involves selecting the addressees and alarm texts as well as configuring the measured values. If an M-Bus command is to be sent, this command must


32

also be selected. Alarm lists must be configured for this purpose.

3.5.3.1 Alarm destinations

This list contains ten entries of addressees (recipients) of alarm reports. A name, the associated telephone number and an e-mail address can be configured for each entry.

3.5.3.2 Alarm texts

For alarm reporting purposes, one of 10 user-defined alarm texts can be added to each alarm defined. This alarm text is sent with the alarm report.

3.5.3.3 M-Bus alarm actions

If an M-Bus command is to be sent in response to an alarm (e.g. to connect a relay to a HYDROMETER HYDRO-PORT control), it is possible to store up to 100 of these commands in the Alarm Action List.

3.5.4 Structure of alarm reports (SMS and e-mail)

The maximum length of both SMS and e-mail alarm reports is 160 characters. The structure of each alarm report is described using an example.

3.5.4.1 Status alarm

Alarms resulting from a status byte check (status byte in the M-Bus telegram) are shown as follows:

Example: Sharky 504566711 [2]: Alarm in meter state(30)Status value alarm

|----- (a) -----|(b) |---------- (c) -------||--- (d) -----|

(a) Meter description; if no description is entered in the device list, the 8-digit meter number is entered automatically.

(b) Alarm number; [1] or [2]

(c) Alarm indication; the value of the status byte is shown as a hexadecimal number in brackets

(d) Alarm text

3.5.4.2 Instantaneous value alarm

An alarm initiated by an instantaneous value below or above the limit is shown as follows:

Example: Sharky 34548085 [1]: 23.400000 > 20.000000 oC

|----- (a) ---| (b) |---------- (c) ----| (d)

Temperature exceeds limit

|--------- (e) ---------|


33



(c) Alarm condition; the configured limit is 20 °C, measured value 23.4 °C, alarm for value exceeding the limit

(d) Unit, if supported (see 6.2.2 VIF values supported in alarm text) (e) Alarm text

3.5.4.3 Intelligent consumption alarm

The intelligent consumption value alarm causes a similar alarm report to that shown for the instantaneous value alarm.

Example: Sharky 504566711 [1]: 0.300000 > 0.240000 m3 Consumption too high

|----- (a) ----| (b) |------- (c) -----|(d) |------ (e) -----|



(c) Alarm condition; the configured limit is 20 °C, measured value 23.4 °C, alarm for value exceeding the limit

(d) Unit, if supported (see 6.2.2 VIF values supported in alarm text)

(e) Alarm text

3.5.4.4 Creating/editing the alarm lists

If the alarm functions are to be used, alarm lists must be created in the IZAR CENTER. You can execute up to 3 alarm actions when an alarm occurs:

• Alarm SMS (only with a GSM/GPRS modem)

• Alarm e-mail (only over LAN interface)

• Send an M-Bus command to a device in the M-Bus network

As already mentioned, you need the following lists:

Alarm action Alarm lists required (name of list)

Optional alarm lists required (name of list)

SMS Addresses Reports

E-mail Addresses Reports

M-Bus command M-Bus command

Proceed as follows to create an alarm list:

• Connect to the IZAR CENTER (as described in one of the options at 3.1.4) and read the status values of the IZAR CENTER.


34

• Change to the “Alarm lists” program view by pressing the button.

• Select one of the 3 alarm lists (addresses, messages, M-Bus commands) by clicking the relevant tab.

To create a new entry in the list, double click the cell to be edited in the alarm list. A cursor appears and you can enter your data. Example of addresses:

Enter telephone numbers in the following format:

• National: Usual form for country without additional preceding noughts, e.g.: 016012345678

• International: Preceded by country code (‘+’ sign), e.g.: +4917212345678

The format with preceding noughts (e.g. 0049…) is not admissible for international telephone numbers!

Example of reports:

Example of M-Bus commands:

When editing the Address field, a dialogue box appears for selecting how to address the M-Bus device to be controlled. Enter the M-Bus command in hexadecimal form in the Command field.

• After you have made one or more entries in the list, write the list into the IZAR CENTER by pressing the button (Write list).

• You also have the option of saving the list in a file by pressing the button (Save list to file). The file is saved as a .csv file, which means it can also be opened and edited with programs such as Microsoft Excel©.


35

• Repeat this procedure for further alarm lists.

Note: If you have already saved alarm lists in your IZAR CENTER or in a file and want to change a list, you can do this in the IZAR@CENTER software by pressing the button (Read list) or button (Load list from file) and then write the list into the IZAR CENTER again or save it in the file.


36

3.5.4.5 Configuration of alarms

If you want the IZAR CENTER to monitor the values of a connected M-Bus device, make sure the following conditions are fulfilled:

• The Service mode is activated.

• A device list has been created and loaded from the IZAR CENTER into the IZAR@CENTER program. A valid read interval must be set for the devices to be monitored.

• The relevant alarm lists have been created, saved in the IZAR CENTER and loaded from the IZAR CENTER into the IZAR@CENTER program.

Proceed as follows to define an alarm for a device:

• Change to the Device reading view, select the desired device and press the button (Read selected device).

• As soon as the device has been read successfully, the data available from the device appear in the read window:

• Double click the value to be monitored. The “Edit alarms..” window appears.

• Activate the alarm monitoring by placing a tick in the “activate” field. You can now edit the alarm settings.

• The value to be monitored is shown in the Measured value field. Select the relevant value if necessary, but this should already be set correctly as a result of double clicking the read window.

• Select how the value is to be monitored (type of monitoring). There are 3 options: 1. Mask: Monitors the device status information (M-Bus status byte). This type of monitoring is useful for generating an alarm for events such as a defect or malfunction of the device. The settings depend on the type of device to be monitored. Please refer to the Communication Description of the device used. 2. Instantaneous value: A simple set/actual comparison is carried out. Example: Monitoring of temperatures, flow rates, current energy consumption, etc.


37

3. Consumption value: Monitors accumulating meter consumption readings such as volume. As this type of monitoring is relatively time-consuming, only maximum 20 consumption values can be monitored with the IZAR CENTER.

• Select if an alarm is to be initiated when the value is to be watched for above (Overflow) or below (Underflow) the reference value.

• Now enter your reference/limit in the Value field. The actual value must not be higher or lower than this limit. The entry varies according to the type of monitoring selected: 1. Mask (Monitoring of status information): Double click the relevant box for each bit to adapt the mask:

The bit mask you are defining here is the error status. This means the M-Bus device reports an error and indicates this in the status byte. The illustration shows the following example: An alarm is to be generated if the M-Bus device has a permanent error. The device reports this error by setting its bit 3 to the value 1. All other bits are to be ignored for the alarm. The mask is therefore as follows:

Bit 7

Fig. 3-7 Alarm mask

6 5 4 3 2 1 0

Value

The status byte is defined in the M-Bus standard (EN13757-3). Bits 0 to 4 have a fixed function and bits 5 to 7 are manufacturer-specific. Ask your M-Bus device manufacturer for further information. 2. Instantaneous value: A simple set/actual comparison is carried out. Example: Monitoring of temperatures, flow rates, current energy consumption, etc. Enter your reference/limit in the Value field. The actual value must not be higher or lower than this limit. 3. Consumption value: Monitors accumulating meter consumption readings such as volume. As this type of monitoring is relatively time-consuming, only maximum 20 consumption values can be monitored with the IZAR CENTER. Enter the reference/limit in the Value field. The actual value must not be higher or lower than this limit. Below the input field you can state whether the limit entered is per read interval, per second, per minute or per hour.

• Now you define in the Action field what actions are to be initiated in the event of an alarm. You can activate or deactivate the actions Send e-mail, Send SMS and Execute M-Bus command in any desired combination. Not more than 3 actions per defined alarm are possible.


38

• The Recipient field is for defining which of the addressees in the Alarm Address List are to receive an e-mail or SMS.

• The Text field is for defining which additional Text from the alarm text list should be send within the alarm message in an SMS or e-mail

• The M-Bus command field is for defining which command in the Alarm M-Bus Command List is to be executed.

• The Status field shows the status of the alarm at the time you read the device list into the IZAR@CENTER software (only appears if the alarm has already been defined).

• You can now define the second alarm if desired (right half of alarm window). Proceed as described above.

• Accept the settings for the alarm by pressing OK.

• The device list now shows you that an alarm is defined for this M-Bus device (the device icon has a red background):

• Now write the device list into the IZAR CENTER and deactivate the Service mode. Alarm monitoring is now active.

Note: How quickly the alarm actions are executed in the event of an alarm condition depends on the read interval you have set. For example, if the interval is set to 1 h, it may take up to an hour until you are informed about the alarm occurrence (e.g. by SMS). The smallest interval is 1 m (once per minute).


39

4 Configuration and test

4.1 Serial/modem interface

The IZAR CENTER is equipped as standard with a serial RS232 interface, to which either a modem or a PC can be connected.

4.1.1 RS232 interface to modem (“Modem” mode)

If you wish to use the IZAR CENTER in a system with a modem, you must set the serial interface of the IZAR CENTER to “Modem” mode. Proceed as follows:

• Connect to the IZAR CENTER over USB or LAN.

• Read out the other settings of the IZAR CENTER by pressing the button (Network service configuration).

• Select Modem on the Serial/Modem tab. Further settings now appear:

• Optional: You can now adapt the interface settings. The baud rate, parity flag and stop bit settings apply to serial communication between the modem and IZAR CENTER, on the serial cable connection between the IZAR CENTER and modem.

• Press the button (Write parameter) to write the settings into the IZAR CENTER the IZAR CENTER then performs a reset and the modem connected is initialized.

• GSM/GPRS modem: If you wish to use a GSM/GPRS modem, tick GSM Modem PIN. A new input field appears in which you must enter the PIN number of the SIM card used (4-digit number). Make sure the PIN number is entered correctly.

• GSM/GPRS modem: After entering the PIN number, press the button (Set new GSM modem PIN number) the IZAR CENTER then performs a reset and the modem connected is initialized.

Note: A PIN number must be entered if a GSM/GPRS modem is used. This means the request for the PIN number of the card must not be deactivated.

4.1.2 RS232 interface to PC (“Serial” mode)

The serial interface of the IZAR CENTER is set for communication with a PC in the ex works state and no configuration of the IZAR CENTER is necessary for this. This means you can connect the IZAR CENTER direct to the serial (RS232) interface of your PC using the enclosed serial cable. This interface is also often used for tasks such as connecting PLC or control systems to the IZAR CENTER. The interface is equipped with automatic baud rate detection in the “serial” mode. Please use baud rates of 300 to 57600 bauds for communication with the IZAR CENTER. 57600 bauds are recommended if you only want to communicate with IZAR CENTER itself. If you also want to communicate with M-Bus slaves on the network use baudrates 300…9600 Baud.

Please note: Depending on the PC hardware and baud rate used, it may be necessary to adapt the settings of the serial interface in the Windows control panel (FIFO buffer). If slow


40

baud rates such as 300 and 2400 bauds are used, the FIFO (send and receive) should be set to the smallest setting or deactivated. At high baud rates like 57600, the FIFO should be set to maximum (both controls to the right). If you have previously connected a modem to the interface and would like to use the interface again for connecting a PC, proceed as follows:



• Select serial on the Serial/GSM tab and press the button (Write parameter).

5 Troubleshooting

5.1 M-Bus devices

5.1.1 Device does not respond

There can be several causes if a connected M-Bus device does not respond.

• Is the IZAR CENTER itself reachable? If not, check the connection and the connection settings.

• Has the correct M-Bus baud rate been selected? Some M-Bus devices do not have automatic baud rate detection. The baud rate is usually either 300 bauds or 2400 bauds.

• Has the correct address been selected? Check whether the right address has been set and if applicable the right address data such as device model and address type.

• Use a DC voltmeter to check that the voltage at the M-Bus connection of the M-Bus device is 30..40 volts. If not, check for a line break.

• None of the devices connected can be read! see 5.1.2 Short-circuit

5.1.2 Short-circuit

Wiring faults, defective insulation or moisture can cause a short-circuit on the M-Bus during the installation or daily operation of the M-Bus network. In this case, none of the M-Bus devices connected can be reached over the IZAR CENTER.

The IZAR CENTER is equipped with short-circuit protection. An M-Bus short-circuit is indicated by the red M-Bus LED flashing at 1-second intervals.

Fault clearance: Localize and clear the short-circuit on the M-Bus line by disconnecting and connecting each branch in turn.

5.1.3 Automatic reading does not work

Check the following items if automatic reading does not work:

• Is the Service mode still activated? See 3.3.1.7 Service mode

• Have the read intervals been set for the M-Bus devices? See 3.3.1.5 Writing device list

• Can the devices be read manually? If no, check 5.1.1 and 5.1.2.

5.2 PC communication

5.2.1 IZAR CENTER search over LAN fails

• Your PC/laptop must be located in the same subnet if the search is to work. If this is not possible, read the currently used IP address/ DHCP name, e.g. from the IZAR CENTER over USB.


45

• Is the LAN cable connected and the LED illuminated at the LAN socket of the IZAR CENTER? If no, check that the correct network cable has been used. A crosslink cable must be used for a direct point-to-point connection to a PC.

5.2.2 LAN communication does not work

• Check 5.2.1.

• Check which TCP-IP port the IZAR CENTER is set to, e.g. using a USB connection.

• Check whether you have set the right TCP/IP port in the IZAR@CENTER software for the logical connection to the device.

5.2.3 USB communication does not work

The IZAR CENTER does not need any special USB driver and is therefore recognized by any operating system. If the connection does not work, try the following:

• Disconnect the device and reconnect it to the PC.

• Use another USB cable.

5.2.4 Serial communication does not work

• Have you set the right COM interface in the IZAR@CENTER software?

• Use only valid baud rates (300 bauds..57600 bauds).

• Is the Modem mode still activated? See 4.1.2 RS232 interface to PC (“Serial” mode)

• Deactivate the FIFO buffer of the serial interface in the system control. Go to Start Settings System Control System Hardware Device Manager, double click the relevant COM interface and deactivate or minimize the FIFO buffer settings.

5.2.5 Modem dial-in does not work

5.2.5.1 Analogue modem

• Do you dial in with the IZAR@CENTER software via a telephone system? Check whether a digit for obtaining exchange line access has been entered before the actual telephone number. Example:

o You must dial the prefix 0 to obtain an exchange line.

o The telephone number of the system is 0981 1234567

The number to be entered is therefore: 0,09811234567 The comma after the first 0 is a dial pause of one second, which is recommended for most telephone systems.

• Do you hear busy tone? Another subscriber is possibly accessing the IZAR CENTER at this moment. Please wait a few minutes and try again.

5.2.5.2 GSM/GPRS modem

• Speech can be heard over the modem speaker on dialling in and the connection is not set up.


46

o Have you dialled the right number? Make sure you use the data number of the SIM card and not the speech number.

o Have you written a PIN number into the IZAR CENTER?

o Has the PIN number been entered correctly?

5.3 Exporting data memory

5.3.1 Problems during FTP upload

Irrespective of whether you would like to export over LAN or GPRS, check the following possible causes of the problem:

• Is the server reachable at the moment? Try to connect to the server with your PC and an FTP program.

• Have the data for the FTP server been entered correctly? Check whether the URL, user name and password are correct and whether a correct path that exists in the FTP server is entered in the Directory field (observe the correct use of capitals and small letters).

• Is the destination on the FTP server write-protected? Change the authorization for the folder on the FTP server and activate write access in this folder.

• Has the right upload interface and a valid upload interval been written into the IZAR CENTER?

5.3.1.1 LAN

• Have you entered a URL under Main FTP or Backup FTP and forgotten to enter the IP address of the DNS server? If URLs are used in the URL field in the Main FTP or Backup FTP tab, the IP address of a valid DNS server must be entered in the TCP-IP settings of the IZAR CENTER.

• Have you entered an IP address under Main FTP or Backup FTP and forgotten to delete the IP address of the DNS server? If you have entered an IP address for the FTP server, make sure that no (0.0.0.0) IP address has been entered for the DNS server in the TCP-IP settings of the IZAR CENTER. Delete the IP address if applicable or enter the IP address 0.0.0.0 in the DNS-IP field.

5.3.1.2 GPRS

• Have you inserted a SIM card and written the GSM modem PIN into the IZAR CENTER?

• Is mobile radio reception adequate? Check this by holding a mobile phone close to the modem antenna and checking the receive quality. If reception is weak, relocate the antenna. If reception is generally poor, a more powerful antenna can be used.


47

5.3.2 Problems during direct reading of data memory

• The “wrong password” message appears on reading the IZAR CENTER. Check that you have entered the right data in the User name and Password fields of the IZAR@CENTER software. The following is set ex works: User name: 0 (number 0) Password: 0 (number 0)

• The “defective memory” or “no memory space” message appears on reading the IZAR CENTER The IZAR CENTER is probably defective. Contact our Customer Support for further help.

• The “no memory!” message appears on reading the IZAR CENTER. This is not a fault. You have read an IZAR CENTER repeater (without memory). The software tells you that no memory functions like write device list, edit alarm lists, etc. are available in this type of device.

5.4 Alarms

5.4.1 SMS is not sent

• Is a suitable GSM modem connected to the IZAR CENTER and is the modem power supply OK?

• Check that the IZAR CENTER is set to Modem mode and that a PIN number has been entered.

• Has an Alarm Address List been created and written into the IZAR CENTER?

• Are the addressee’s telephone number and format in the Alarm Address List correct?

5.4.2 E-mail is not sent

• Are the connection data for the mail server set correctly?

• Have you entered a URL under eMail and forgotten to enter the IP address of the DNS server? If URLs are used in the POP-URL or SMTP-URL field, the IP address of a valid DNS server must be entered in the TCP-IP settings of the IZAR CENTER.

• Have you entered an IP address under eMail and forgotten to delete the IP address of the DNS server? If you have entered an IP address for the mail server, make sure that no (0.0.0.0) IP address has been entered for the DNS server in the TCP-IP settings of the IZAR CENTER. Delete the IP address if applicable or enter the IP address 0.0.0.0 in the DNS-IP field.

5.4.3 E-mail/SMS received by wrong addressee

• Check that the right addressee has been selected in the device list entry of the M-Bus device.

• Check the Alarm Address List.


48

5.4.4 Alarm action over M-Bus not executed

• Check that the M-Bus device which is to receive the command can be reached over the M-Bus.

• Check the address type in the M-Bus Alarm Command List. Make sure the right address and baud rate have been entered and that the command has been entered correctly. The M-Bus command must be supported by the device. Enter a complete M-Bus command (from start to stop byte) in the Command field of the M-Bus Command Alarm List.
